Absolutely not, though that is more due to the moon and other celestial bodies being declared terra nullius by the Outer Space Treaty in the late 60s. Something about 'common heritage of mankind.' http://en.wikipedia.org/wiki/Outer_Space_Treaty

I feel like calling Oceania a continent is misleading. The continental area is Australia, but the functional region of Oceania extends past the continental plate, so it's not really a continent per se.

Starfish, you are inaccurate. Since Canada has so man lakes, it is, actually, by ONLY LAND ARE (Excluding Inland waters and rivers), smaller than both the USA and China. But the USA is not larger than China. Although, many, including the UN, say USA is bigger although they are not. They added water area which would make a one square km island actually measured 44 square km. With Alaska, it is totally exaggerating completely. So the Actual order is:
Russia
China
USA
Canada...
SO Actually USA does steal the third spot :)

DJ1 you are right about the statistics according to land area. However, land area is not the same as total area. Think of it this way. That is like saying that Niagara Falls is not part of the US or Canada because it is in water and water is not taken into the area of a nation. The water in which Niagara Falls lies in is cut metaphorically where the countries determine it. Without that cut, Niagara Falls would maybe become limbo land and not be part of any country. Nice to see that there are WonderWhy viewers on jetpunk though.

OK, so if you're going by land ONLY then the order is Russia, China, USA, Canada. But most sources count inland water and water within 5 miles of the shore, which puts it at Russia, Canada, China, USA. That would be fine, but many sources are biased and include water 10-15 miles offshore of the US ONLY.

In addition to being the two smallest on the list, common map projections make Peru and Chad look smaller than they are since they are near the equator. That might be part of the reason many miss those.

I think this quiz'es name is wrong. I assume the data was taken from Wikipedia. I checked the article "List of countries and dependencies by area" and ordered the countries by LAND area, instead of TOTAL area. By land area the top 5 would be: Russia, China, USA, Canada, Brazil. By total area the top 5 would be: Russia, Canada, China, USA, Brazil. I suggest that you remove the "Land" from the quiz'es name.

good point and I never realized that the US was actually larger than Canada in terms of land area. I guess it's just so hard to see in 2D projections. Very interesting. Also, Chad drops off the list and Niger gets on if you look at land area only, and China is #3 regardless of metric. Must be using something other than Wikipedia...

US has less land area than China btw. The US counts not just coastal teritorries but sea territories also, the only country to do so.
In terms of land area alone its Russia>China>USA>Canada.
In terms of land area + lakes it's Russia>Canada>China>USA. (imo this is the term you should use, as the rest of the world does when it thinks of land territory. After all, under the lakes is... land)
In terms of land area + lakes + coastal waters it's Russia>Canada>China>USA
In any of those ways China is larger than the US.
Even if you were to clue in the sea territories, China would probably still beat the US but due to the tiny Spratly Islands dispute it can't get a conclusive figure.

In other words the China land + inland lakes area is: 9,596,961 sq km (excluding Hong Kong, Macau and Taiwan).
USA land + inland lakes area is: 9,526,468 sq km. The figure up on the list there is an inflated one that includes not only the coastal waters, but also sea waters (that the CIA factbook uses, but no other country does).
See notes 3 and 4 on this: http://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_area

As you can see from actually reading what I wrote, China is far larger when looking at *land* area. This quiz, however, includes all inland bodies of water, which pushes the *total* area of the US up ahead of China (mostly thanks to the Great Lakes). So yes, I do know for a fact that China's land area is much larger than the United States', because it is a fact.

Actually even including inland water china is still bigger than the US some sources include territorial waters for the US but not for most other countries and that is what puts the US above China. If you include the same things for both countries china is bigger.

fair enough that USA counts the inland waters, as many countries do, China included - but the US also counts the coastal waters (no other country counts this). On top of that it also includes all sea territories, vast swathes of ocean well out in the Pacific and Atlantic. Read the smallprint in the CIA factbook/ website.
The reality is China 9,640,821km2, USA 9,526,468 km2.

If one quiz listing all of the countries of the world doesn't accept Greenland on the basis that it is part of Denmark, why does another quiz about the largest countries not count Greenland as part of Denmark? Kind of renders Greenland as terra non grata, no?

Can I ask for an explanation of why overseas territories are not counted as part of the nation's land area? Bringing up the Denmark and Greenland issue, Greenland is a piece of land on Earth. Therefore it makes up part of the earth's surface. What you are asking for is the nations on Earth with the largest land area, and whether it is physically connected to the mainland of the nation that owns it or not, Greenland is still a part of Earth, and is under the control of Denmark. I just don't see how water separating the two parts should prevent it from being counted. Can someone please explain?

Greenland as part of Denmark should probably count; although there is a debate as to whether it "belongs" to Denmark, is a sovereign nation, or somewhere in between.
Not including territories is sensible in that overseas claims such as those on Antarctica are not universally accepted

Well, Greenland is not a real country. Although they have a language and permanent population. They still count as territory for Denmark.(Unfortunately, this is not a part of Denmark)So it is not a country of part of Denmark.
The end.

Sudan is still the 3rd largest country in Africa, even without the small part that is now South Sudan. So yeah, it still beats out everything except for Algeria(which is number one) and DR Congo(which is number two).

@Alvar - your comment is one of the most amusing examples of attempting to establish oneself as credible I have ever seen. You say that you live in China to let us know you know what you are talking about (because you have obviously seen the entirety of the country) but say you are a foreigner so that we realise you aren't biased towards China.

After taking it again following the update on August 28, 2018, I got them all again with 1:28 left at about 6:24:35 PM on February 5, 2019. Completing this quiz again increased my point total by 5, to 751 and my level from level 28 to level 29.
